Tom,

With the advent of Onboard diagnostics (OBD) the whole scope
thing is pretty much prehistoric at this point.
I use my laptop to set up Carol's Corvette and the late El
Camino. All of the information that was once displayed on a
oscilloscope CRT is now digitally available to anybody with
a laptop and the appropriate software package.

Subject: Re: [BlindHandyMan] Audible level modification


Hey Lary,
I don't remember an optacon with a vibration thingie on the
chest, but such a thing was done here at Smith-Kettlewell
using a TV. camera and an array of vibrating pins.  Had you
really been desperate enough it's possible you could have
used it on  scope, but they were hideously expensive to
build and unreliable as all heck

Actually we have a design for an audible scope which I think
might work on engine analysis devices, although i don't know
what the scope pattern looks like to be sure.  It doesn't
work with multi-trace patterns, but with simple single trace
stuff it works fine.

On the level, no, i was just thinking of a single pager
motor turning on and off, one side of level, it'd be on all
the time, other side of level, it'd be pulsing on and off,
so level is where it just starts to pulse.

Tom
